[ckan-dev] Prelim SPARQL endpoint - request for test

[Pierre-Yves Vandenbussche]

Ross,

It doesn't seem that the endpoint contains an explicit information on the
accessURL format such as SPARQL endpoint.
Could you please help me find out how to fetch this information using the
last release ?

Thanks,

Pierre-Yves Vandenbussche.
